The Influence of the Use of the Warning Triangle in Reduced Visibility on the Speed of Vehicles

Abstract

This article deals with the effect of using the warning triangle in a real traffic situation in reduced visibility during night time. The focus of the study is the change in the speed of passing vehicles in relation to this non-standard situation. The coefficient of the dangerousness was used to evaluate and describe the drivers‘ behaviour. In the framework of this research, different possibilities of avoiding a collision or its consequences were considered in the considered range of distances of 30 to 50m between the warning triangle and the imaginary obstacle.
